If you have an Android device with Samsung’s TouchWiz UI, you would have observed that when you delete an app, or a group of apps from an app screen, that space will not be automatically filled with apps present in the next screen.
For example, let’s say you have 6 pages (screens) of apps on your Galaxy S Android phone. When you delete a few apps from a screen, say screen 4, ideally, the apps present in the next screen, that is screen 5, should occupy the space of the deleted app, or apps. Otherwise, over time, when you delete a few apps from a screen, only empty spaces show up, with apps in the next screens.
This should have been automatically avoided but somehow, Samsung leaves it to the users to re-arrange the apps to fill the screens completely.
On the screen which is next to the screen where there is an empty space for an app, touch Menu and select edit. Long press an app and when it moves from its places, drag it to the left part of the screen. When the previous screen appear, let go the app.
When you’re done re-arranging apps, touch Menu again and select Save.
